Abstract
The utility module relates to a sound collecting alarm module, comprising a sound-controlled amplification circuit, a monostabillity trigger circuit, a multi-oscillation alarm circuit and a wireless emission module circuit. An output signal of the sound-controlled amplification circuit is transmitted to the monostabillity trigger circuit. Output signals of the monostabillity trigger circuit are sent to the multi-oscillation alarm circuit and the wireless emission module circuit respectively. The sound collecting alarm module adopts sounds (footsteps, and vibration sounds, crashing sounds, etc., of objects) as trigger signals, uses a wireless emission module to send an alarm signal, and can be used to give the anti-theft alarm in places of storehouses, factories, shops and the like.
Description
Technical field
The utility model relates to a kind of alarm module, particularly be a kind of sound collection alarm module.
Background technology
Traditional anti-theft warning circuit, cardinal principle adopts wired alarming or dialing alarm mode, and alarm velocity is slower like this, is subjected to allocation of facility condition restriction on every side, and alarm distance is short.

Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of sound collection alarm module of the present utility model, comprise acoustic control amplifying circuit 1, monostalbe trigger circuit 2, multi-harmonic-oscillations warning circuit 21 and radio emitting modular circuit 22, the output signal of described acoustic control amplifying circuit 1 is transferred to monostalbe trigger circuit 2, and the output signal of described monostalbe trigger circuit 2 is sent to respectively multi-harmonic-oscillations warning circuit 21 and radio emitting modular circuit 22.
Described acoustic control amplifying circuit 1 adopts piezoelectricity singing piece BC as the audio sensor collection signal, described piezoelectricity singing piece BC is in series with potentiometer RP, the output terminal of described piezoelectricity singing piece BC is connected to field effect transistor VF, and the output terminal of described field effect transistor VF is connected with resistor R2, resistor R3 and capacitor C1.
Described monostalbe trigger circuit 2 is made of the first time-base integrated circuit IC1 and peripheral resistor R4 and the capacitor C3 that connects thereof.
Described multi-harmonic-oscillations warning circuit 21 is made of the information ring device BL that the second time-base integrated circuit IC2 and output terminal thereof connect, and the periphery of described the second time-base integrated circuit IC2 is connected with resistor R5, resistor R6 and capacitor C4.
The external Receiving Host emission of the antenna TX frequency electromagnetic waves alerting signal that described radio emitting modular circuit 2 connects by FDD-5 transmitter module IC3 output terminal.
When piezoelectricity singing piece BC did not detect voice signal, monostalbe trigger circuit 2 was in stable state, the 3rd pin output low level of the first time-base integrated circuit IC1, and multi-harmonic-oscillations warning circuit 21 nonoscillatory, information ring device BL is sounding not.Simultaneously, radio emitting modular circuit 2 is because of Triggerless, and FDD-5 transmitter module IC3 does not send alerting signal yet.
When the monitored space that has the burglar to walk close to piezoelectricity singing piece BC is committed theft, piezoelectricity singing piece BC is transformed to electric signal with the voice signal that detects, this signal produces trigger pip after field effect transistor VF amplifies, making only, steady state trigger circuit 2 is triggered and is overturn, become temporary stable state by stable state, the 3rd pin of the first time-base integrated circuit IC1 becomes high level by low level, 21 work of multi-harmonic-oscillations warning circuit, and information ring device B sends chimes of doom.Because the first time-base integrated circuit IC1 output high level signal, this signal is input to the 2nd pin of FDD-5 transmitter module IC3, and deliver to the 3rd pin of FDD-5 transmitter module IC3, be modulation signal input end CP, high-frequency signal to emission is modulated, the antenna TX that FDD-5 transmitter module IC3 output terminal connects is that external Receiving Host is launched modulated frequency electromagnetic waves alerting signal, can be used for the burglar alarm in the places such as storehouse, factory, shop.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
